【摘要】 本文用特殊的方法证明了各种分区布拉德福系数具有α_m=α^?的关系.且在证明中指出分多区情况下布拉德福定律同洛特卡定律的一致性.同时得到两个有用的参数估计式.即T=e^?;α_H=T^1/R.更多还原

【Abstract】 In this paper,we have proved the Bradford coefficients relations of various grouping methods,which satisfy am = with special approach. The identity of Bradford law and lotka law under the condition of more groups was pointed out in our proof.Meanwhile we have got two useful estimation parametric equations Vi2,T=,aH = T.更多还原
